STOVE.

Specication of Letters Patent No. 23,624, dated April 12, 1859.

To all who/m, it may concern:

Be it known that I, DAVID STUART, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Gras- Consuming Cooking- Stoves, and that the following is a full, clear, and exact description of the principle or character which distinguishes it from all other things before known and of the usual manner of making, modifying, and using the same, reference being had to the accompanying drawings, of which- Figure l is a vertical longitudinal middle section. Fig. 2 is a top view with part of the top plate removed. Fig. 3 is a plan of the bottom of the stove. Fig. t is an interior view of the grate front, and Fig. 5 is an elevation of the grate front.

My invention consists in an improvement in gas consuming cooking stoves described and represented as follows: The front of the grate is divided horizontally into two compartments a, I), and these are each subdivided into vertical apartments c, d, by the partitions c, c', which are so arranged as to form a zigzag course for the air passing through them as indicated by the arrows in Fig. 4. The partitions are open above and below alternately as clearly shown in Fig. 4, which detains the air and heats it etfectually on its passage to the distributing pipes L, c. The upper chamber a opens at each corner by passages m into the distributing pipes h, L, which pass across the top of the tire chamber f on each side and convey the heated air into the discharge pipe r. This pipe, perforated with numerous small holes, has its central part g projecting over the tire so as to increase the surface of discharge and also for the purpose of dividing the ame and products of combustion and causing them more eifectually to impinge upon the back boilers s, s. The lower chamber b, opens through passages t into distributing pipes c which pass down on each side of the stove front and are thence continued on each side of the stove into the iue space fw under the oven cc where they are connected by a cross pipe e which is perforated with numerous small holes to allow the heated air to escape and mingle with the heated products of combustion. The hot air escaping from the distributing pipes above and below assists in perfecting the combustion of unconsumed gases and improves the draft, and. that escaping under the oven assists in conveying heat to the bottom of the oven. The cold air enters through the apertures al, a2, in the grate front a3.

Vhat I claim as my improvement in gas consuming cooking stoves isl. The distributing chamber or discharge pipe r formed with a central projection g and supplied with heated air from the grate front through pipes /L as set forth.

2. I claim the discharge pipe a located under the oven and supplied from the grate front by pipes .7c as set forth.

I claim dividing the grate front horizontally into two series of heating chambers as set forth.
